Hi @Mohit, it's never too late to get into DevOps. Since you've worked in the IT infrastructure for quite some time now, it'll be easier for you to pick up DevOps concepts. You will have to work with tools that you probably haven't used before but I am sure you'll pick up easily(they are not very difficult).
DevOps would indeed be a great career switch to make especially since it has been booming in the IT industry.
